MAINTENANCE & ADJUSTMENTS

Clamp Base Locking Nut Adjustment

In the event the Locking Lever rotation is
insufficient to ensure smooth operation of
the clamp base, very minor adjustments to
the Clamp Base Locking Nut can be made
with the supplied 17mm socket. Tighten or
loosen the locking nut in very small incre-
ments to provide more clamping pressure or
running clearance as needed.

Adjusting the  Clamp Jaws

The Quick Action Clamps will need minor adjustments
according to what string type, construction, and gauge
you are using.

To adjust the gap (clamping pressure) between the
clamp jaws, insert the string through the racquet as if
you were beginning the main strings. Clamp the strings
and pull tension. If the string slips through the jaws of
the clamp,  tighten the clamp by compressing the clamp
jaws together by hand while turning the Adjustment
Knob, in the clockwise direction.  If the clamp leaves
impressions or damages the string, it may be exces-
sively tight and should be adjusted by turning the hex

screw counter clockwise to open the gap between the jaws. The clamp jaws should be
cleaned periodically to be free from dirt, oil and any string coating for them to grip properly.

Note

: The string clamps supplied with your stringing machine can accomodate tight string

patterns such as badminton. Depending on the string pattern, the clamp may spread the strings
slightly which will not compromise the quality of the string job.  String clamps designed
specifically for badminton racquets are available.

Quick Action Clamp Base Removal

Quick Action clamp bases can be removed
from the turntable for maintenance or clean-
ing by removing clamp stop located at the
end of the slot in the turntable. To remove the
clamp stop, remove the two screws holding
the clamp stop in place from the underside of
the turntable.  Lift the clamp stop out of the
slot, slide the clamp base to the end of the
slot and lift it out. Replace the clamp base
and clamp stop in reverse order.
